Jeremy Lin said becoming a better shooter will open up much of his game. And he thinks being entrenched as a starter finally will help him solidify his yearlong attempt to remake his jumper.

The Nets point guard, known for driving the ball, estimates he has put up 5,000 jumpers weekly. But it’s not how many he takes, but how he takes them, which he says will help. And the mechanical tweaks he has made are starting to take hold.

“I know the work I put in, so going into this season, I’m just confident in my shot. I’m more confident in my shot today than I’ve probably ever been. I’m hoping that carries through,’’ Lin said. “I changed my form last year, which is why I dipped. I wasn’t as comfortable with it and I spent another summer, made a couple more tweaks. Now it’s definitely the most fluid motion when I’m shooting from deep.

“The biggest thing is consistency. The other one was too hard on my legs. When I had fresh legs, I’d shoot it well. And when I didn’t, I wouldn’t. The reason was because I was jumping too high, bringing the ball too far back. It was just taking a lot of my body, and the season wears on you. Changing my shot, it’s much more repeatable. It saves my legs and it’s less contingent on how much energy I have.”

Lin pointed to the Warriors’ Stephen Curry and Klay Thompson as having repeatable shots, smooth efficient motions no matter how deep they shoot.

So he tried scaling back from a two-motion shot to a one-motion shot near the end of 2014-15 with the Lakers, and spent last season in Charlotte struggling to get it to stick. After shooting .424 with the Lakers, and a career-best .369 from deep, he saw those numbers drop to .412 (his worst since his rookie campaign) and .336 last season.

“You’re talking about 10 years of muscle memory,’’ Lin said. “That’s why last season there was definitely a dip. There were times I’d get in the game and revert to my old shot, then I’d go to my new shot, then I’d be somewhere in-between.

“Last year was so frustrating for me shooting-wise. After the game, I’d just be like, ‘Man, I don’t even know what form I’m using right now.’ This year, all the way through camp it’s felt great. It’s felt exactly the way I want it to feel.”

Lin credited shooting coach Doc Scheppler and trainer Josh Fan. Now he also will be working with Nets director of player development Adam Harrington, Kevin Durant’s former shooting specialist.

“Jeremy’s putting a lot of work into his jump shot. With him, I’d say it’s more mental, just trusting it,’’ Nets coach Kenny Atkinson said. “Jeremy’s a driver, he’s an attacker. He’s a get-to-the-free-throw-line guy, so that’s his first intention. … I’d like to see him trust that shot. You still want him driving and attacking, but you want him to trust that open catch-and-shoot. He shoots it better than people think.”

Both Lin and Atkinson said it will improve from being a starter.

“Knowing how much I’m going to play and having the ball in my hands and getting in that rhythm and that game-feel [helps]. I’m a big-time rhythm and game-feel and confidence and comfort player,’’ Lin said. “When I’m comfortable and confident, I know what I’m getting myself into, I tend to play better.”

The numbers back that up. A career .419/.322 shooter as a reserve, that vaults to .441/.361 as a starter, including .461/.461 last year.

“For him it’s a big deal. It helps him with his confidence,’’ Atkinson said. “I hope that’s going to give him another shot of adrenaline, a shot of impetus to be starting for us, and that’s going to help him take another step in his game.”

Greivis Vasquez practiced fully for the first time on Friday, and said he felt “great.”
